WINDOW-VENTILATOR.

EPLECIFICATION forming part of Letters Patent No. 331,796, datedDecember 8, 1885.

Application filed April 20, 1883. Serial No. 92,370. (130 model.)

To all whom, it may concern:

Be it known that I, PHILIPP (J. Knarrnn, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and usefulImprovementin Show-Window and Cellar Ventilators,which improvement; isfully set forth in the following specification and accompanyingdrawings, in which- Figure 1 isa cross vertical section of a show windowequipped with my improved ventilating device. Fig. 2 is a perspective ofmy improved Window.

The present invention relates to show-win dow and cellar ventilators forstores; and the object is to provide a system of ventilation or draftsfor the show-window and the cellar, so that the show-window will notreceive or deposit moisture in cold weather and obstruct the View fromthe outside, and to enable the cellar beneath the store-floor to beventilated during the summer months, all of which will now be set forthin detail. I

In the accompanying drawings, A represents the store-floor, and B theshow-window floor or platform. 0 is the cellar-space below theshow-window. D represents an open ing through the floor along theforward end or side of the show-window, which opening is designed tocommunicate directly with the cellar O. In case the show-window extendsover the line of the cellar, as is the case in some instances, I designhaving fines communicating with the opening D and extending back underthe floor A to the cellar. The front or both front and sides of theshowwindow are provided with an opening or openings, E, having in saidopenings screens F. These openings are located in the sides of the showwindow frame below the floor B. The space below the floor B is dividedinto two compartments by means of a partition, G. The front compartment,H, is in communication with the openings D E, which extend practicallythe entire width of the glass, and the rear compartment, I, is incommunication with the opening J, having a suitable door, K. The rearcompartment, I, may be used for a storage-room, and the partition G isdesigned to prevent air from the openings D E passing into the storethrough the opening J when the door K is opened. The show-window floor Bhas near its outer end an opening, L, communicating with the chamber H.The upper end of the show-window has in the outer face,or in both thesides and the ends of the frame, openings M, provided with screens N.These openings have glass transonis or doors 0, hinged on the inside. Prepresents a cord attached to the transom, and running thence overpulleys Q to the inner side of the show-window, so that the said transom0 may be opened by a person inside the store by the depending cord P.

R represents the show-window glass, and S the door communicating withthe interior of the store.

The operation of the invention is simple and readily understood.

On thefloor A is a slide or registeigU, which projects forward so thatit covers the opening D in the floor. The under side of the floorB issimilarly provided with a rogiste1,V, which closes the opening L.

In cold weather the transom O is opened, as shown by dotted lines, andthe upper register,V, drawn back, as shown in the drawings. The lowerregister, U, is pushed forward so as to cover the opening D. The coldair from the outside therefore enters the opening E, passes through theopening L, ascends to the transom-opening M, and passes out, therebycooling the interior of the showwindow,causing the air from the outsideto enter feeely and circulate, so as to bring the temperature the samewithin that it is without, and thus prevent condensation from takingplace on the glass.

In warm weather the register V and transom O are closed and the registerU opened, so that the cellar can be ventilated and the gases and noxiousvapors passed out through the openings D E.

Having described my inventiomwhat I claim A show or bulk window of thecharacter described, having ventilating-openings at top and bottomextending substantially the en tire width of theglass, a floor above thelower openings, said floor provided with corresponding openings near thewalls of the window, all

have hereunto set my hand, this 26th day of February, 1883, in thepresence of witnesses.

the said openings provided with valves by which they may be opened orclosed, and an opening between the cellarand theiower openings in thewindow, and means for closing 5 said opening at wilhsubstantially asdescribed,
